Below
you can select the board size based on the tallest chess piece. My
standard size board is for a 3" chess set and I refer to it as a 3"
board. For the spacing between the shelves, I allow an extra 1/4" above
the tallest chess piece. For example, on a standard 3" board, the
spacing between the shelves is 3.25". On a 4" board the spacing 4.25".The overall size of a standard 3" board with this frame is 22 1/4" x 34 1/4".
If you select a different size board below, you are given the number of
inches to add or subtract from those dimensions based on this frame.
